Luke Bonham

Research Coordinator

Luke grew up in Southern California before attending UC Berkeley. Graduating with a degree in business administration, he joined the UC San Francisco Memory and Aging Center in 2013. Prior to joining the Memory and Aging Center, he worked in Dr. Dena Dubal’s lab at UCSF to study sex differences in mouse models of neurodegenerative diseases. He currently works with Jennifer Yokoyama, PhD, and Howard Rosen, MD, to study the genetics of healthy aging and neurodegenerative diseases.

In his free time, Luke likes to ski, camp and hike.

Andreas Lazaris

Clinical Research Coordinator

Andreas graduated from UC Berkeley in 2014 with a B.A. degree in cognitive neuroscience. In his time at Berkeley, Andreas completed his honors thesis under Dr. Gil Rabinovici as an undergraduate researcher in the laboratory of William Jagust, assessing the function of PET biomarkers in the diagnosis and disease course of Alzheimer’s disease and frontotemporal dementia. Andreas also worked as an undergraduate research fellow in the laboratory of Dr. Liana Apostolova at the UCLA Mary S. Easton Alzheimer’s Disease Research Center.

Since graduating, Andreas has joined the UCSF Memory and Aging Center as a Clinical Research Coordinator, working under Dr. Gil Rabinovici at the MAC and in the Jagust Lab at the Helen Wills Neuroscience Institute at UC Berkeley. Andreas coordinates the group's PET imaging projects and clinical trials, focusing on clinical phenotypes of disease and their relation to FDG, amyloid, and tau PET imaging measures. Outside of the world of neurology, you can find Andreas riding his bike from cafe to cafe throughout the East Bay and catching a local live show whenever possible.

Rik Ossenkoppele, PhD

Postdoctoral Scholar

Rik Ossenkoppele is a postdoctoral researcher at the UCSF Memory and Aging Center. He completed his PhD degree at the Alzheimer Center of the VU University Medical Center in Amsterdam, the Netherlands, in 2013. His past research focused on (amyloid and glucose metabolism) PET and MRI imaging in relation to neuropsychological performance in Alzheimer’s disease patients. He currently utilizes these techniques to better understand clinical heterogeneity and cognitive reserve in dementia. Dr. Ossenkoppele’s work at the UCSF MAC is supported by BrightFocus and a Marie Curie FP7 International Outgoing Fellowship.

Fitness, Aging and Stress (FAST) Study for Family Caregivers

The purpose of this study is to explore the benefits of regular physical activity to adult women and men providing care to family members who have been diagnosed with Alzheimer’s disease or dementia.


Alainna Brown

Research Associate

Alainna graduated from Washington University in St. Louis in 2014, where she studied neuroscience and biomedical physics. She joined the UCSF Memory and Aging Center in July 2014 and assists Dr. Suzee Lee in neuroimaging and genetic studies of rare dementias.

Miguel Angel Santos, MD

Clinical Research Fellow

Dr. Miguel Angel Santos is a clinical research fellow in Dr. Gorno Tempini’s language group since 2013. His research focuses on studying the characteristics of both speech and limb apraxia present in patients across different neurodegenerative disease syndromes. His research methodology includes correlation of neuropsychological and psychophysical behavioral measures with brain images using various neuroimaging analysis techniques. He was born in Washington, DC where he lived until moving to Spain at the age of 17. He completed medical school at the University of Salamanca and his neurology residency at the Hospital de la Santa Creu i Sant Pau in Barcelona, Spain. He research is supported by a grant from the Alfonso Martin Escudero Foundation based in Madrid, Spain.

Joanna Hellmuth, MD, MHS

Behavioral Neurology Fellow

Joanna Hellmuth, MD, MHS, joined the UCSF Memory and Aging Center in July 2014 as a behavioral neurology fellow. She provides care to patients with various neurodegenerative disorders and collaborates in the evaluation of patients for the Alzheimer's Disease Research Center (ADRC) and frontotemporal dementia program project grant.

Lisa Kritikos

Research Coordinator

Lisa Kritikos joined the Memory and Aging Center in 2014. Her primary role is managing the New Approaches to Dementia Heterogeneity research, which follows patients with the goal of learning more about dementia to improve early detection and clinical care for patients as part of the UCSF Alzheimer's Disease Research Center.

Natanya Russek

Research Coordinator

Natanya Russek graduated from the University of Wisconsin – Madison in 2014 with a degree in neurobiology. At Wisconsin she contributed to research on the development of a stem cell therapy for stroke under the guidance of Dr. Matthew Jensen.

Natanya joined the Memory and Aging Center in May of 2014. She coordinates the study Frontotemporal Dementia: Genes, Imaging and Emotions. This observational study aims to better characterize neurodegenerative diseases such as frontotemporal dementia with the goal of developing better diagnostic tools for the diseases.

Carolyn Fredericks, MD

Behavioral Neurology Fellow

Carolyn Fredericks, MD, joined the UCSF Memory and Aging Center in July 2014 as a behavioral neurology fellow. She completed her AB/ScB degrees at Brown University in classics and neuroscience, then received her MD from Stanford University, where she also completed her internship in internal medicine. She went on to a residency in neurology at Johns Hopkins Hospital and UCSF. Her prior research experience includes studies of genetic influences on corticolimbic circuits in individuals with bipolar disorder, functional neuroimaging studies of reward processing in both healthy and bipolar individuals, and exploration of the inflammatory response to psychosocial stress in healthy young women. She is currently working with Drs. Bill Seeley and Virginia Sturm in an effort to better understand the effects of genetic risk for Alzheimer's disease on psychosocial measures and intrinsic brain connectivity.
